ROTATION VELOCITY SENSOR OF GAS-TURBINE AIRCRAFT ENGINE ROTOR Russian patent published in 2011 - IPC G01P3/48 

FIELD: medicine.

SUBSTANCE: rotation velocity sensor of a gas-turbine aircraft engine rotor transforming rotation frequency into a radio signal containing an electromagnetic rotation frequency transducer of the gas-turbine aircraft engine rotor into an electric signal in the form of at least two inductance coil - signal and reactor, respectively arranged on a constant magnet core placed near to teeth of a tooth gear fixed on a running shaft of the gas-turbine aircraft engine rotor, a frequency-code converter connected to the signal inductance coil, an adapter setting an operating mode of an aircraft engine and connected to an output of the converter, a radio module with an integrated antenna to transmit a radio signal and connect to an input of a remote automatic aircraft engine control system, connected to an output of the adapter, an electronic switch and a rectifier connected to the reactor. The rectifier is connected by its own outputs to the converter, the adapter and the accumulator, respectively, and the electronic switch is connected by its own inputs to the adapter and the accumulator, and an output - to the radio module for delivery of radio module switching-on signal according to the certain operating mode of the aircraft engine.

EFFECT: reduced number and weight of cables and electric connectors, higher reliability of the electronic control system, simplified binding of the gas-turbine aircraft engine and lower maintenance costs.
